I've got a problem with server side binding on the combobox. 

A select list is created in the controller an it is passed a selected value. The list is passed to the view via a view model and then binded to the combobox via BindTo. The correct item is displayed/selected in the combobox when open the page. The problem is that when I open the combobox it shows the text "System.Web.Mvc.SelectList" which isn't a value that exists in the SelectList!

If I view the source I see that the combobox is initialized with "System.Web.Mvc.SelectList" as the selected value?! 

Is this a bug or am I missing something?
 
I've attached a small sample project that visualizes the problem.

Did you find a resolution to this yet?

I just ran into the same problem.Tested with dropdownitem and it also puts the type name as the selected value.

Hello,

This happens when the ComboBox UI component and the SelectList collection have same name. The ComboBox tries to find string value ( which will be used to select correct item ) in the ViewData. Hence when ViewData.Eval("Cars") is called then the returned value is "System.Web.Mvc.SelectList". In order to avoid this behavior I will suggest you to change the combobox name.
